MICROFABRICATION OF A 3D, ELASTIC CELL MICROENVIRONMENT WITH NANOSCALE PRECISION USING LAYER-BY- LAYER DEPOSITION
Markela Ibo, Kiran Bhadriraju, Darwin Reyes-Hernandez
Here we present a unique method to generate a customized cell microenvironment that allows for the positioning of specific components of the extracellular matrix, and other polyelectrolytes, at a precise distance from the matrix surface; thus, providing a variable, well-coordinated material that could be tailored for essential cell-surface interactions. Weakly cross-linked melamine formaldehyde (MF) microparticles were packed in microfluidic channels and polyelectrolyte multilayers were formed, layer-by-layer, on top of them. The MF microparticles were then dissolved and matrices with an elastic modulus of 10 kPa, and capable of maintaining cells alive for at least 24 h, were obtained.
